Start by building the base and internal structure of the oven. The first step is to measure the outline for the base and set with cinder blocks. The key to building the block is to check level often and you use plenty of mortar.
Once the oven's structure is chest high, saw grooves in the block and cut rebar to lay in a crisscross pattern. This will create the foundation for the oven floor when the concrete is poured. Put in 3 inches of sand, cover it with tar paper, and pour concrete over.
Use thinstone veneer to face the oven. The veneer comes in corners and flats. It goes on easily with mortar, just cover and firmly press in place. Set the oven floor using a heat resistant mortar.
With the floor set, carefully piece together the domed oven. Using the same heat resistant mortar, joint the pieces together. Then build the remaining block work. Cut and attach the ledge and insulate the area around the oven.
